Within CMPC BioPackaging, the flow of fiber is between the four subsidiaries that comprise it, mainly oriented to the Corrugated business. The latter is a concrete application of circular economy where waste is used instead of sub-products of one subsidiary to produce another.

Fibras plays a fundamental role: it recovers the final product from the market for the subsidiaries. Specifically, through this business, fiber discards are purchased: recycled cardboard (OCC), DKL, and duplex, which is done nationally through generators (especially retail) and collectors. This fiber is selected and transformed into bales of recycled paper. Also, the plants of CMPC Biopackaging; Sack Kraft Chillán and Argentina, Cordillera, and Softys; Talagante, Puente Alto, Altamira, Gachancipá and Pando directly import recycled paper.

Once collected, Fibras – as waste manager – sends bales to the paper production plants, such as Cordillera, and the molding production plants, Chimolsa. At the same time, the recycled paper production plant sends the recycled paper to the cardboard packaging production plants. Also, the cardboard waste produced at the packaging plants is baled at each packaging plant and sent for reprocessing at the paper and molded pulp production plants. There are also direct transfers of offcuts from Boxboard Maule, Envases Impresos Osorno, Tiltil and Buin to Cordillera and/or Moldeados.
